After some invetigation, it seems that the machine boots, but has no
access to the network.  And indeed, the information about the network for
this machine says:

eth0/enp24s0f0, Ethernet, configured rate: 10 Gbps, model: Intel Ethernet
Controller X710 for 10GbE SFP+, driver: i40e

All is fine on another machine in the same infrastructure that has a
different networking configuration:

eth0/eno1, Ethernet, configured rate: 25 Gbps, model: Mellanox
Technologies MT27710 Family [ConnectX-4 Lx], driver: mlx5_core, SR-IOV
enabled
eth1/eno2, Ethernet, configured rate: 25 Gbps, model: Mellanox
Technologies MT27710 Family [ConnectX-4 Lx], driver: mlx5_core, SR-IOV
enabled

thanks,
